Scalable Hybrid Speech Codec for Voice over Internet Protocol Applications
With the advent of various web-based applications and the fourth generation (4G) access technology, there has been an exponential growth in the demand of multimedia service delivery along with speech signals in a voice over internet protocol (VoIP) setup. Need is felt to fine-tune the conventional speech codecs deployed to cater to the modern environment. This fine-tuning can be achieved by fur...

متن کاملPacket Loss Concealment of Voice-over IP Packet using Redundant Parameter Transmission Under Severe Loss Conditions
This paper describes an outline of a project for developing a VoIP codec that can be used under a very severe communication environment where half of the packets drop. The codec is based on G.729 CS-ACELP, and a packet loss concealment (PLC) methods with redundant information will be used for enhancing speech quality. First, we assessed the importance of G.729 parameters, where we found that pa...
